I recommend stepping down with a flat end mill for roughing, then step up with the ball end for finishing, ball ends do not cut well on the tip...
you dont have to change your drawing (-: just select millimeters in the units field of the post, as below. the default is to send 'document...
you are correct, you 'setzero' at the surface of the board. the machine has 7 coordinate systems. the machine coordinate system (MCS) accessed...
I recall seeing someone use a chamfer bit with spiral flutes, that will give less tool pressure and a much better finish. I think it was this...
you might want to consider this sort of thing... [MEDIA]
I make that 1.016 mm per rev, Blackbox defaults to 8x microstepping, so my calculator shows... steps per mm: 1574.803150 or...
The best and easiest way to do this is to use bCNC (you dont have to be using it to run the machine!) open the gcode in bCNC click the editor tab...
so now you need to search that .nc file for that pair of lines, namely. G1 X307.877 Y-334.554 G2 X308.196 Y-334.873 Z-11.5 I0 J-0.319 that...
I think I see a misunderstanding here: GRBL is the firmware that runs on the microcontroller in the controller, like the BlackBox, xPro or bare...
then the other place to look is the fusion post. there are settings for minimum arc radius and minimum arc chord. They interact, they must not be...
hohum, no errors here, neither in your supplied .nc file nor in the one I generated from that operation. Did you change any GRBL settings like...
naaa, steppers motors dont know where they are. this is an internal error generated when the arc definition is faulty. Gcode arcs are defined as a...
I would first clean and adjust all the v wheels, some of them are not touching during some of those moves. Then I would check belt tension, I use...
We are going to need more information in order to help you. What drivers? What interface to the drivers? (a Break out Board, or a USB controller,...
indeed. but the principle still applies (-: I seldom jog less than 0.1mm which is about 4 thou (event hough on Z I can jog 0.01mm which is about...
a jog of 0.001 is only useful if your hardware has 1000 steps per mm or more. my Z does 0.01mm per step, so would only actually move every 10...
sure, but it helps (-: knowledge is power. did you do as Peter instructed?
my goal was not so much 'a number' but rather 'the same number on all of them' since I am a little OCD like that. I had the thought that...
I tighten my belts on my router with a spring balance, the type used by fishermen. I pull to 12kg. I first tried 6 but that proved to be too little.
if you are generating your gcode from Fusion, turn on smoothing for that toolpath so that it generates fewer lines of gcode. [MEDIA]
